Removal of instabilities of the higher derivative theories in the light of antilinearity
Biswajit Paul, Himangshu Dhar, Biswajit Saha
Theories with higher derivatives involve linear instabilities in the Hamiltonian commonly known as Ostrogradski ghosts and can be viewed as a very serious problem during quantizati…
Ghosts in higher derivative Maxwell-Chern-Simon's theory and symmetry
Biswajit Paul, Himangshu Dhar, Biswajit Saha
Ghost fields in quantum field theory have been a long-standing problem. Specifically, theories with higher derivatives involve ghosts that appear in the Hamiltonian in the form of…
Treating Ostrogradski instability for Gallilean invariant Chern Simon's model via \mathcal{PT} symmetry
Biswajit Paul, Himangshu Dhar, Mangobinda Chowdhury +1
The Ostrogradski ghost problem that appears in higher derivative theories containing constraints has been considered here. Specifically we have considered systems where only the se…
